Different DPIs work differently, but the following instructions will apply in most cases:
Be sure to follow the manufacturer’s instructions regarding priming and loading your DPI with the correct dose of dry-powder medication.
Breathe out slowly and completely for three to five seconds.
Put your mouth on the mouthpiece and inhale deeply.
Hold your breath for 10 seconds.
Repeat these steps as instructed by your provider until you’ve taken the prescribed number of doses.
